AI Technical Summary
Technical Problem
In existing flotation methods for separating chalcopyrite and pyrite, the collector selectivity is poor, and it relies on a large amount of lime, resulting in high reagent costs, significant environmental impact, and low separation efficiency.
Method used
By using a chalcopyrite collector containing propyne esters, along with a frother and an inhibitor, flotation can be carried out over a wide pH range to achieve highly selective collection of chalcopyrite and effective inhibition of pyrite, while reducing the amount of lime used.
Benefits of technology
It significantly improves the grade and recovery rate of copper concentrate, reduces reagent costs and environmental impact, and is suitable for large-scale industrial production.

Abstract
本申请提供一种浮选分离黄铜矿‑黄铁矿的方法，涉及矿物浮选领域。将包含黄铜矿、黄铁矿的待选矿物和黄铜矿捕收剂进行混合、浮选，得到黄铜矿精矿和黄铁矿尾矿；黄铜矿捕收剂的结构通式为：。该黄铜矿捕收剂利用其丙炔酯基亲固基团对黄铜矿表面铜活性位点的高选择性亲和力，以及对黄铁矿表面铁位点的惰性，实现了从药剂分子结构上对黄铜矿的精准识别和捕收，显著提高了铜精矿的品位和回收率；R基为疏水基团，朝向矿浆，使得黄铜矿颗粒的表面疏水性显著增强，从而能够粘附于浮选气泡并上浮。
